When the part or all of MTC device in packet is roamed, interior other MTC device place nets no matter are grouped
Whether network there is congestion, and for the network that congestion does not occur, corresponding MME is to this part MTC device in packet
Congestion control is not carried out.When there is the equipment of roaming state in the packet equipment for causing MME congestions, this is refused first
The message of a little peripatetic devices sends, and the message for continuing other local packet equipments sends, if now congestion state terminates,
Then after other local packet equipment completion messages send, message transmission is carried out to peripatetic device；If still failing to terminate
Congestion state, then using aforesaid interim packet congestion control scheme, do not differentiate between local or peripatetic device.
Below in conjunction with the accompanying drawings alternative embodiment of the present invention is described and is illustrated.
